To all whom, it may concern:

Be 1t l nown that 1, JAMES W. FULLER, J r.,

- a citizen of the United States, residing at Catasauqua,-in the county of Lehigh and State of'Pennsylvania, have invented certain new and useful Improvements in the Mode of Producing Seli-Lubricating Car-Wheels, of

- hub portion and of establishing a connection vention.

-between"certain separated chambers thereof,

The principal objects of my invention are, first, to form a selfdubricating car-wheel with an integral (i e., an undivided) hub portion having chambers cast therein to receive a lubricant and an axle second, to connect certain of said chambers with each other by forming openings in. certain of the walls there- 'of after the wheels has been cast, so as to per mit of the flow of a lubricant from a certain chamber to another certam chamber thereof, WhlOl'l conducts the same to a chamber adapted to receive an axle, and, third, to close the openings formed inone 'ofthe walls to render a certain chamber ada table'for the reception of a lubricant an to permit the same by the openings formed in another wall to pass from the receiving-chamber into a distributingchamber, which. conducts the lubricant to an axle terminating in a third chamber formed in. the hub.

The nature and scope of my invention will be more fully understood from the following description, taken in connection with the ac companying drawings, forming part hereof, in w iich 'Figure 1 is a vertical sectional view of a self-lubricating car-wheel, illustrating the chambered hub portion after the casting of the-wheel embodying the features of my in- Fig; 2 is a detail view illustrating in section the formation of openings formed in contiguous vertical walls of the hub por tion to connect certain of the chambers thereof with each other. Fig. 3 is a similar View illustrating the manner of closing the opening formed in one of the contiguous vertical walls of the hub portion, and Fig. 4 is a crossectional view taken on the line as as of 3.

Referring to the drawing, a is a earn/heel the rim a, flange a, as Well as the spokes o of which are of the usual Well-known con- 55 strn ction. The hub portion, however, formameter than the chamber l)".

ing the subject-matter of my resent invention consists of a hollow integra body I), composed of three vertical walls 6, b and bi and two annular walls b and If". These walls form three chambers b b and 5 of which.

the chamber b is connected with the annular chamber 57 by means of a curved slot I)", cast through the annular partition-Wall b The inner annular chamber 6 serves to receive a car-axle, (not shown,) which by filling this chamber closes the communication of the chamber 6 with the chamber b, otherwise established between the same, as shown in Fig. 1. The chamber 5, which by means of an opening I), cast into the vertical Wall b,

' communicates with the exterior of the'hub l is adapted to receive a lubricant, such as oil,

'which is introducedinto the same through When the central chamber 3 the opening 5 5 however, is filled by an axle, (not shown,) the oil in the receiving; chamber 1; is pre vented from entering the outer annular cham ber and from thence through the slot 11 into the inner annular chamber 5 rendering a hub so formed impel tive. In order to permit of the flow oithe oil from the receiving chamber b" into the annular distributing chamber 3), the outer rtical wall 5 and inner-vertical Wall f0 ring a partition-wall between the chambers and b, are pierced. by a drill or other suitable tool, and preferably three openings 0 and c in the walls I) and b are formed, of which the openings 0 in the partition-wall b are preferably arranged adjacent to the periphery of the interior walls of the chamber 6 as shown in Fig. 2. These openings 0 are preferably inclined,

so as to permit of the exit of all the lubricant introduced into the chamber b into the distributing-chamber b which is of larger diln'order to permit of the filling of the receivingechamber b up to the central opening 5 the openings 0 in the outer wall b are closed by plugs in the manner shown-in Fig. 3. These plugs d by tightly fitting the openings 0 render the.

partitionaV all b liquid-proof, and thuspermit of the lilling of the receiving-chamber -bf= close to the opening b Having thus described the nature and ob-- jects of my invention, what I claim as new,

and desire to secure by Letters Patent, is

a 1. The mode-of forming a self-lubricating car-Wheel which consists in. first forming a wheel having a hollow hub portion com osea of vertical andhorizontalwalls integra each other and dividing the hub intotwo an-- nular communicating chambers-andlaisingle chamber arranged at a right angle thereto,

then forming openings in oneofthe outer and in the intermediate 0 said vertical Walls of the hub so as to connect said single chamber with the outer of said annular chambers, then clos-- mg the openingsformed in one of the outer walls so as to render the same liquid-proofto' a central opening" cast therein, to per mit of the filling of the single" chamber with a wheel having a hollow hub portion, com osed' of three vertical and two horizontal wai s, di-

'viding the hub into two annular chambers connected with each other by an annular opening formed in one of said horizontal walls separating said chambers from each other, and into a single chamber arranged at outer annular chamber with said single chaincentral opening an a right angle thereto and communicating with one'end of the inner annular chamber, and with. the exterior of the hub by an open- .ing formed in-one of the vertical walls and centrally to said inner annular chamber ,then drilling holes through said outer perforated vertical wall and through the intermediate of said vertical Walls so as to connect said her, then plugging: the" holes formed. in the outer perforated vertical wall to close the openings drilled therein, to'form a chamber capable of receivin a lubricant up to saidt'o permit the same to flow into said outer annular chamber and from thence by said annular opening into said inner annular chamber or an axle placed therein when the Wheel occupies a vertical or operative POSltlOll;

In testimony whereof have hereunto set my signature in the presence of two subscrib ing' witnesses,
